From the DMG, put the 'darcs' executable wherever you wish (e.g. /usr/local/bin).

From a suitable folder, obtain the latest versions of GTS, Gerris, and GfsView.

darcs get http://gfs.sf.net/darcs/gerris/gerris-stable
darcs get http://gts.sf.net/darcs/gts-mainline
darcs get http://gfs.sourceforge.net/darcs/gfsview/gfsview-mainline

We will install these in /opt/gerris to keep them isolated from the rest of the system. This requires /opt/gerris/lib/pkgconfig to be added to your PKG_CONFIG_PATH. This directory does not exist yet - it will be created in the next step.

Check your version of automake. Currently (November 8, 2007) this installation procedure works with automake 1.6.3 which is
on your system by default. Delete any more recent packages. In the future, more recent packages may be needed.
